Reflections on IaC using Terraform

This post provides useful notes and examples on working with infrastructure as code projects using Terraform, focusing on techniques for querying from external providers and structuring variables. It also covers tips on using data blocks, variables, outputs, sensitive variables, locals, iterating over resources, and utilising modules. Additional information includes working with built-in functions, validation rules for variables, managing state using CLI commands, and experimenting with the HCL syntax using terraform console.
